HighlightThe best salinity for the thallus growth of K. alvarezii is 32 mg/LThe salinity indicates the osmotic balance of K. alvarezii seaweedThis osmoregulation process affects the nutrient absorption of K. alvarezii seaweedThis study aims to develop the availibility of superior seeds of K. alvareziiAbstract Kappaphycus alvarezii is one of the leading commodities in Indonesian waters. Demand for this commodity is quite high, as reflected in the increasing volume of exports each year. Fulfillment of these demands is obtained from the production of cultivation. Generally farmers get natural seaweed seedlings, namely cuttings from existing seaweed. The continuous use of seeds from nature can cause deterioration in the quality and quantity. Handling the problem of quality deterioration from seaweed seeds originating from nature, can be overcome by multiplying the seeds through tissue culture methods in vitro. In term of tissue culture techniques method, the most important thing to note is environmental parameters. An environment parameter that changes suddenly such as salinity can inhibit the growth of seaweed. Thus, this work is attampting the different salinity treatment on seaweed explants K. alvarezii. This study aims at determining (weight) the explants of K. alvarezii with a comparison of the different salinity levels in the in vitro tissue culture method. The method used in this study was a completely randomized design (CRD) with the different salinity treatments namely 30, 31, 32, 33, and 34 ppt. The results showed that the different salinities influenced the growth rate of K. alvarezii seaweed explants with the best explant growth at the salinity of 31 ppt, while the lowest growth value was obtained at 34 ppt

Highlight Investigated in heavy metal bio-accumulation in red mullet (Mullus barbatus) and Common pandora (Pagellus erythrinus) collected in Zliten Coast, Libya.Based on the samples collected, the muscle tissue of fish species may be considered suitable for human consumption.The metal concentration levels observed were in range of acceptable limits proposed by regulations of WHO and FAO.AbstractThe current study aimed to determine the heavy metal concentration like as copper (Cu), zinc (Zn), lead (Pb), cadmium (Cd) and mercury (Hg) in the liver, gills, gonad and muscles in two fish species (red mullet (Mullus barbatus), and common Pandora (Pagellus erythrinus) collected from the Zliten coast in Libya. The levels of heavy metals were determined by using an atomic absorption spectrophotometer (AAS). The results showed that the concentration of heavy metals in the sampled fishes less than the permissible limits for human consumption. In addition, the bioaccumulation for Cu, Pb, Cd, and Hg by both fish species was: liver >gills > gonads > muscles, while Zn follows the sequence: gonads > liver > gills > muscles.

HighlightBullet tuna (Auxis rochei Risso 1810) has been identified (measured, weighed) and analyzed.The resource status of bullet tuna has been estimated based on body shape and age group.LWR curve is implemented to describe and express the age group of bullet tuna (immature, adult/mature, old)This study has resulted the composition and ratio of bullet tuna that is suitable to be caught, fit for consumption and worthy of maturationAbstractBullet tuna (Auxis rochei Risso 1810) or tongkol lisong (Indonesian) is important for human consumption and health as well as an income source for fishers and coastal communities. Its utilization problems are over exploitation, catch domination by immature groups, and the threatened stock security of the bullet tuna (BLT). This research aimed to determine the status of the prospective parent of bullet tuna caught in the Lesser Sunda region, particularly from the Alas Strait to the Indian Ocean, West Nusa Tenggara (WNT). Meanwhile, the data were collected from July to September 2020 (2nd transitional season) at the Tanjung Luar Fishing Port, East Lombok and a dependent survey method was adopted with sampling, interview, observation, and documentation techniques. Fork length and body weight data were used to estimate the length and weight relationship, growth pattern, condition factor, fish age group, and catch worth. The primary and secondary data were processed quantitatively using several equations. The growth pattern of bullet tuna was minor allometric (b = 2.875), worth selling (K > 1.00), and the majority was adult fish or mature group. The LWR model is . This condition indicates the bullet tuna is worth catching and worth spawning, so that it is eligible to be a potential broodstock candidate to support a sustainable management of BLT fisheries. Furthermore, fishers have applied the code of conduct for responsible fisheries (CCRF) in supporting the sustainable development goals.

HighlightCatfish aquaculture wastewater contains organic matter that exceeds the quality standard of 68.75 mg / L and 72.48 mg / L.Tutut Jawa snail (F. javanica) can reduce organic matter in waste by up to 92%.Susuh Kura snail (S. testudinaria) can reduce organic matter in waste by up to 87%.Catfish aquaculture wastewater treatment with snails only takes 8 hours. Abstract The residual or wastewater from the cultivation process that is discharged directly into common waters can reduce the quality of the waters because it contains a lot of organic material from organism feces and feed residue, so it needs management first. The purpose of this study was to determine the ability of Javanese snails and freshwater gastropods to reduce total organic matter in catfish culture waste. The research method used was the experiment with 2 factor Factorial completely randomized design, namely the measurement time (4, 8, 12, and 16 hours) and the abundance of the Tutut Java snail and freshwater gastropods (100%, 75%, 50%, 25%, and control) with 5 repetitions. Tutut Java snails were taken from the pond at UPR Sumbermina Dau and brought to the laboratory. The results obtained in the treatment with the addition of Tutut Java snail, the total organic matter content decreased at 75% snail density by 90% (from 68.75 mg / L to 5.31 mg / L) at the 12th hour. The treatment with the addition of Freshwater Gastropods at a density of 25%, the total organic matter content decreased by 87% (from 72.48 to 9.35 mg / L) at the 8th hour. Water quality during the study was in a condition that could tolerate the Tutut Java snails and freshwater gastropods. The conclusion is that the addition of Tutut Java snail and / or freshwater gastropods can reduce the total organic matter content to the water quality standard.

HighlightMarine debris can be as a treat for coral reefBranching coral is the most affected by marine debrisPlastic marine debris commonly found in all research location, especially from fisheries and daily activityAbstractA coral reef is one of the important ecosystems, however, the existence of coral reef is threatened. Several factors can be a threat to the coral reef, such as marine debris. Research about marine debris on coral reefs in Indonesia has not much been done. This research aims to identify marine debris that is found and impacted, to identify the impacts caused, and to identify the life forms most susceptible to being affected. This research was conducted in Kelapa Island, Kelapa Dua Island, and Harapan Island by using the Belt Transect method sized 20 x 4 m2 with four repetitions at each station to determine coral reef life form, and type of marine debris. The data was analyzed by using the Correspondence Analysis (CA) to determine the correlation of marine debris and the affected life forms of coral reefs. The result showed the plastic marine debris was found in all stations. Six life forms were affected by marine debris, and the most susceptible life forms that affected were massive and branching. The most dominant impact category on coral reefs was tissue loss with algal growth (TLAG).

Enterocytozoon hepatopenaei (EHP), a microsporidia parasite known to hinder shrimp growth by infecting its hepatopancreas, is recently an emerging infection for Litopenaeus vannamei farms in Indonesia. The present study was conducted to investigate the relationship between nitrite and ammonia concentration with EHP infection in the super-intensive ponds. Shrimps and water samples were collected from six ponds in aquaculture super-intensive ponds with a stocking density of 5,000 shrimps in each pond which is located in Pasuruan, Lamongan, and Tuban Regency, Indonesia. The water sample was taken to the laboratory for the measurement of ammonia and nitrite. The samples of ammonia and nitrite were detected by spectrophotometer, and the PCR was used to detect 18S rRNA of EHP. The PCR analysis that showed two positive samples of L. vannamei, from the ponds with a high concentration of ammonia and nitrite, were infected by EHP. The statistical analysis showed a significant correlation between ammonia and nitrite with the prevalence of EHP infections, where the Pearson correlation (r) was 0.980 and 0.943, respectively. There was a high prevalence of EHP infection with the increase in nitrite concentration and ammonia in pond four and pond six. The concentration of over 1mg/l of ammonia and nitrite could influence EHP infection prevalence in the shrimp farms. Highlight ResearchAmmonia and nitrite concentration influence the prevalence of Enterocytozoon hepatopenaei infection in Super intensive ponds.The estimated prevalence of Enterocytozoon hepatopenaei was 16.7%.PCR amplification analysis was used to detect the 18S ss-rRNA of Enterocytozoon hepatopenaei and 510-bp was obtained.

HighlightThe sex ratio of tiger prawns in the waters of female groceries is 1.08 times higher than that of males.The growth characteristic of male and female tiger prawns is negative allometry, but the male and female body shapes are fat.Fishing mortality, capture mortality, exploitation rate, female tiger prawns are higher than males, but total mortality and natural mortality male tiger prawns are higher than females.The male infinitive growth is longer than the female.AbstractThe windu shrimp (Penaeus monodon) is an economically important fishery species in the waters of Tarakan. The shrimp is highly demanded for frozen seafood industry that makes its market price range attractive from Rp. 50,000 (USD 3.37) to Rp. 70,000 (USD 4.72)/kg. This can cause the species to be potentially exploited. However, due to lack of data, the exploitation status of the windu shrimp is unknown. Hence, the present study was carried out to determine the absolute growth, mortality, and exploitation level of the windu shrimp in Juata waters of Tarakan. Sampling of the shrimp using experimental trawling net was conducted four times between June and August 2020 in the waters of Tarakan. Morphometric data of the windu shrimps including sex, total length, carapace length, and total weight were recorded and analyzed. The results showed that the sex ratio of male and female tiger prawns was 1:1.08. The maximum growth of male and female shrimps was estimated at 26.875 and 21.435 cm respectively. The size of the male shrimps caught during the sampling ranged between 8.7 and 22.5 cm, and was estimated to be at 13 to 67 days old respectively. Maximum growth of male shrimp was estimated at 26.875 cm that could be achieved within 411 days. The size of female shrimp caught during the sampling ranged from 9.8 to 19.3 cm with an estimated age of 21 to 87 days respectively. The maximum growth for female shrimp was estimated at 21.435 cm, and achievable within 377 days. The mortality of male and female shrimps was not significantly different at 110.3% and 110.1% respectively. The fishing mortality for male and female shrimps was recorded at 19% and 22.5% respectively. The level of exploitation of male and female shrimps was slightly different at 17.2% and 20.5%, respectively. Finally, the natural mortality for male and female shrimps was at 91.3% and 87.5%, respectively.
